The following document and code intends to carry out a complementary methodological Exploratory Data Analysis from survey data in coquina (Donux truculus) in a historic context review of FEMP_AND_04 project.
In this case, we analysed biological component like lengths structure, density indicator and fishery yield in CPUE type.
This analysis are essential to give advice to Junta de Andaluacía through management plan to D. trunculus (Agricultura & Rural, 2023).
2 AREA DE ESTUDIO
La zona de distribución de la coquina objeto de este análisis es en base a la aplicación de la regulación marisquera española, relacionado con la producción. Para ello, el litoral andaluz se dividió en diferentes zonas de producción (ZZPP) las cuales se encuentran definidas en la Orden de 15 de julio de 1993 (BOJA nº 85 de 5/8/1993).
En esta Orden se declaran las zonas de producción y protección o mejora de moluscos bivalvos, moluscos gasterópodos, tunicados y equinodermos marinos de la Comunidad Autónoma de Andalucía, fuera de las cuales quedará prohibida la su recolección. Esta norma delimita zonas de producción de moluscos bivalvos a lo largo del litoral andaluz en los cuales se encuentran los puntos de muestreo establecidos en el seguimiento temporal de D. trunculus en el litoral de Huelva llevado a cabo por el IEO (Marco & Delgado, 2022) (Figura 2.1).
Figure 2.1: Mapa con los puntos de muestreo establecidos en el seguimiento temporal de D. trunculus en el litoral de Huelva llevado a cabo por el IEO.
3 ENFOQUE DE AED
These data, spetially length frecuencies, must be weighted to the
sampling estimates, because they are just a subsample. This approach has
a logic used to POBLACIONAL (Figura 3.1) and
COMERCIAL samples (Figura 3.2);
Figure 3.1: Poblacional sample scheme
Figure 3.2: Comercial sample scheme
En este codigo autocontenido, analizaremos tres componentes de interés. Estructuras de tallas, densidades poblacionales e Indice de reclutamiento.
4 BASES DATOS
En este trabajo se deben revisar todos los componentes que se tienen en cuenta, para ello, investigadores del IEO prepararon una descripción de cada fuente , caracteristicas y su escala temporal. La mayoría de estos dsatos son compuestos por el monitoreo y seguimiento científico de Donax trunculus en el Golfo de Cádiz lque lleva a cabo el IEO y AGAPA.

| vB k | 0.48 | Revisar | |
| EDAD MÁXIMA | EM= log(0.01)/M | Revisar | |

En cuanto a aspectos reproductivos, la reproducción de coquina es entre los meses de Febrero – julio, con un maximo de desove entre mayo- julio, coincidiendo con la veda (Agricultura & Rural, 2023).
4.1 Leer y juntar Data Base
4.1.1 Bases de Longitudes
# Datos 2020 size and dens and abundance join
size2017 <- read.csv2(here("Data", "Anterior a 2020", "data_ieo_2017_def.csv"), dec=".")

Se deben leer las dos hojas POBLACIONAL y COMERCIAL por separado y
luego unir.
Recordar wque las bases de densidades previas al 2020 estan en la misma base que las longitudes
